Mitsubishi PCA-A42KA Thermistor
A very basic thermistor is a type of resistor whose rated resistance is altered by the amount of, or lack thereof, heat. They notify the system when a certain temperature in increasing or decreasing. The system control board must know the temp in order to make a decision on what needs to be done.
What are the indications that my main thermister is about to go out?
- The blower may fail in its attempt to engage full speed spinning
- The heating and AC system could possibly not operate because of any damaged thermistor

If you are going to be buying or ordering do your best and cross-check the correct model and also make a visual inspection in order to be sure the proper replacement thermistor is being ordered. You do not have to install the part by yourself. Hire a pro in your community to do the job for you.
Feel free to download your manual for help.
